ESA’s Celeste mission launch 1

On 25 March, the first two satellites of the Celeste LEO-PNT in-orbit demonstration mission will lift off aboard Rocket Lab’s Electron rocket from the company’s Māhia Launch Complex in New Zealand. Celeste will play a pioneering role in elevating the future of Europe’s satellite navigation capabilities. As Europe’s first initiative …

Overview

Destination: Sun-Synchronous Orbit
Mission: Navigation

Sun-Synchronous Orbit Rocket Lab Launch Complex 1A Rocket Lab Launch Complex 1, Mahia Peninsula, New Zealand

The European Space Agency (ESA)'s LEO-PNT (Low Earth Orbit Positioning, Navigation and Timing) demonstrator mission will feature a 10-satellite constellation demonstration mission that will assess how a low Earth orbit fleet of satellites can work in combination with the Galileo and EGNOS constellations in higher orbits that provide Europe’s own global navigation system. This launch will lift 2 “Pathfinder A” satellites built by Thales Alenia Space and GMV to a 510 km altitude Low Earth Orbit.

Electron

Family:
Configuration:

Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.
